Homework Help: excretion

Posted by biology on Sunday, November 8, 2009 at 11:50pm.

Question:

which is an example of excretion?
a) release of sweat from the sweat glands
b) removal of carbondioxide from the lungs

Please tell me what is the answer. I thought both urea(from the sweat) and CO2 are products of excretion? In fact, my textbook says that "carbon dioxide is an excretory product that is excreted by the lungs as gas in expired air". It also says that "excess mineral salts and nitrogenous waste products such as urea are excreted by the skin as constituents of sweat". So how am i supposed to do that multiple choice question??? Please help!
